Based on the experience of having restored two of these from a similar state, and given the probable condition of this car, including the seized/worn/rusty/broken and missing bits you can't see.....

You can expect to spend around another £15000 on parts, and take at least 1500 hoursdepending on your skill level/knowledge, and how much room and facilities you've got.Some bits are irreplaceable, and will have to be re-manufactured from raw materials, but theP&W register have been working on this problem.

Amateur restorations will obviously save on labour costs, but usually take longer because you learn as you go, and the result generally doesn't have that sharp presentation, or has to compromise on originality.

So a well-presented near-original Warwick with continuous history bidding at £16000 is a bit of a stealand explains why running versions of these cars seldom change hands.
